These tender steak bites are seared to a golden brown and combined with sautéed mushrooms in a rich, fragrant garlic butter sauce. Cooked in under 30 minutes, this dish strikes a perfect balance between savory flavors and satisfying textures, making it ideal for a simple yet impressive dinner. Fresh herbs add brightness, and optional lemon wedges bring a subtle citrusy finish to each bite.
The method involves searing sirloin cubes in olive oil until browned, then cooking mushrooms until golden before adding butter, garlic, thyme, and parsley. The steak returns to the pan to soak in the buttery sauce briefly, creating a luscious coating. This low-carb, gluten-free dish pairs well with crusty bread or a fresh salad.
I was standing at the stove on a Tuesday night, tired and convinced I had nothing good to make, when I spotted a pack of steak in the fridge and a container of mushrooms about to turn. Twenty minutes later, I was eating what became one of my most-requested dinners. The garlic butter clung to every cube of meat, the mushrooms soaked up all that flavor, and I realized sometimes the best meals happen when you just start cooking.
The first time I made this for friends, someone asked if Id been secretly taking cooking classes. I laughed because all I did was sear some steak, toss in mushrooms, and let butter and garlic do the heavy lifting. That night taught me that impressive food doesnt have to be complicated.
Ingredients
- Sirloin steak: I cut mine into bite-sized cubes so every piece gets a crispy edge and stays tender inside, plus it cooks in minutes instead of needing a long rest.
- Olive oil: Just enough to coat the steak and help it brown without sticking to the pan.
- Salt and black pepper: Simple seasoning that lets the beef flavor shine through, and I always use freshly cracked pepper for a little extra bite.
- Cremini or white mushrooms: I quarter them so they get golden and caramelized on the edges while soaking up all that buttery garlic goodness.
- Unsalted butter: This is what makes the sauce rich and silky, and using unsalted means you control exactly how much salt goes into the dish.
- Garlic cloves: Freshly minced makes all the difference, filling your kitchen with that unmistakable aroma that tells everyone dinners almost ready.
- Fresh parsley: A handful stirred in at the end adds brightness and a pop of color that makes the whole dish feel more alive.
- Dried thyme: It brings a subtle earthy note that pairs beautifully with both the beef and the mushrooms.
- Lemon wedges: Optional, but a quick squeeze over the top cuts through the richness and wakes up every flavor.
Instructions
- Prep the steak:
- Pat those cubes completely dry with paper towels because any moisture will steam the meat instead of searing it. Toss them with olive oil, salt, and pepper until every piece is lightly coated.
- Sear the steak:
- Get your skillet screaming hot over medium-high heat, then add the steak in a single layer without crowding. Let each side sear undisturbed for a couple minutes until you see that deep golden crust, then pull them out and set aside.
- Cook the mushrooms:
- Toss the mushrooms into the same hot pan and resist the urge to stir constantly. Let them sit and brown on one side, releasing their moisture and turning golden at the edges.
- Build the garlic butter sauce:
- Turn the heat down to medium, drop in the butter, garlic, thyme, and parsley, and stir for about a minute. Your kitchen will smell incredible.
- Combine everything:
- Add the steak and any juices back into the pan and toss everything together for a minute or two. You want the meat warmed through and every bite coated in that garlicky butter.
- Finish and serve:
- Taste it, adjust the salt if needed, scatter some extra parsley on top, and serve with lemon wedges on the side for anyone who wants a bright squeeze.
One night my neighbor knocked on the door just as I was plating this, and I invited her to stay for a bite. She ended up texting me the next morning asking for the recipe, and now she makes it for her book club every month. Its funny how a simple pan of steak and mushrooms can become part of someone elses routine too.
Choosing Your Steak
Sirloin is my go-to because its affordable, flavorful, and doesnt need much fuss. If youre feeling fancy or have a little extra in the budget, ribeye or tenderloin will give you an even richer, buttery texture. Just make sure whatever cut you choose is well-marbled and cut into even cubes so everything cooks at the same rate.
Making It Your Own
Ive added a splash of white wine to the mushrooms before the butter goes in, and it created this incredible depth that made the whole dish taste like something from a French bistro. You can also swap thyme for rosemary, toss in some red pepper flakes if you like heat, or stir in a spoonful of Dijon mustard at the end for a tangy kick. This recipe is forgiving and loves a little improvisation.
Serving Suggestions
I usually serve this with crusty bread to soak up every drop of garlic butter, but its just as good over mashed potatoes, cauliflower rice, or a pile of buttery egg noodles. A simple arugula salad with lemon vinaigrette on the side balances out the richness perfectly.
- Try it over creamy polenta for a cozy, restaurant-style presentation.
- Pile leftovers onto toasted baguette slices for an easy next-day appetizer.
- Toss with pasta and a little pasta water to stretch it into a full meal for six.
This dish reminds me that you dont need a special occasion to cook something that feels special. I hope it becomes one of those recipes you turn to on busy nights when you still want to sit down to something really good.
